The normal valance number of silicon is 4, so with Si 2- one knows that silicon now has 6 electrons in it's valence shell.
Zinc has 2 valence electrons.
Calcium has 2 valence electrons, like all Group 2 elements.

Alkaline earths have 2 valence electrons.
There are 2 electrons in valence shell of calcium. :-)
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
Zinc has two valence electrons.
